Cable Management, flameshield, sealants - Nelson Fire Stop Products.
    

  
 
  
Multi-Cable Transit is based on a simple but effective design. It consists of a rectangular metal frame suitable for floor or wall installation, which is available in single or multiple units. Each frame contains an arrangement of Tecron™ elastomer modules grooved to fit snugly around cables, pipes, or conduit passing through the frame. The Tecron™ modules expand when exposed to heat, providing a continuous seal even if cable jackets disintegrate. The entire assembly within each frame is locked in position to prevent dislodgment and the spread of fire and the products of combustion.
   
Transit Frame  The transit frame is the housing into which the other components are fitted.
MCT Lubricant (Tallow)  Used when packing. Allows the insert modules to slide easily over each other.
RTV-106 Sealer  For armored cable. Sealer should be applied in the grooves to seal the space between the armor and the cable sheath in navy cables, and the groove in the interlock of industrial cables.
Compression Bolt  When tightened, the bolt applies pressure to the compression plate sealing the grooved insert modules around the cables.
End Packing Standard  End packing assembly is bolted into place to provide a fire and watertight seal above the compression plate. The standard end packing assembly is used when both sides of the transit frame are accessible.
End Packing Special  The special end packing assembly serves the same purpose as the standard and is used when the transit frame is accessible from only one side.
Compression Plate  The compression plate acts as a pressure plate above the internal assembly.
Stay Plates  Stay plates are inserted between every completed row to help distribute compression forces within the frame and to keep modules from dislodging under high pressure conditions.
Grooved Insert Modules  Grooved insert modules are available in seven module sizes to accommodate a range of cable/pipe from 5/32" to 3-3/4" O.D. They fit snugly around the cable or pipe to form an airtight, watertight seal when compression applied in final assembly step.
Spare Insert Modules  Solid modules are used to fill voids or allow for future addition of cables. They are available in 3 module sizes.
Fill-in Insert Strips 
Used to fill space gaps. Available in 5 and 10mm thickness. Strips are 120 mm long and are split to allow cutting at any desired length.
